Actually I made this project for real history maps, but got an idea that it is possible to create a fantasy world as well.
This map is about one of most popular fantasy world. You can see all main characters, regions and cityes. Also you can go read description of all events.
Chronocon is an open project. If you want to edit this map, you can write to firstname.lastname@example.org and I will give an editor permission. Or you can just create copy of this map. (See documentation)
